12-Week Coding Roadmap
Setup & First Program
Go to replit.com (free, no install). Create a Python project. Type print("Hello World") and run it. Learn: variables, input/output, basic math operations.
Logic & Decisions
If/else statements, comparison operators, logical operators. Build: a calculator, a grade checker, a simple quiz game.
Loops & Lists
For loops, while loops, lists, dictionaries. Build: a to-do list app, a number guessing game, a contact book.
Functions & Files
Writing reusable functions, reading/writing files, error handling. Build: a password generator, a diary app that saves to file.
Projects & Problem Solving
Start solving problems on HackerRank (Easy). Build a bigger project: a quiz app with score tracking, or a simple expense tracker.
Choose Your Path
Web Development → Learn HTML/CSS/JavaScript. Data Science → Learn Pandas/NumPy. App Development → Learn Flutter/React Native.
The Golden Rule
Code every single day. Even 30 minutes daily beats 5 hours on weekends. Coding is like a muscle — it grows with consistent practice, not cramming.
